SEWING-MACHINEY TRIMMER.

SPECIFICATION forming part of Letters Patent No. 513,008, dated January16,` 1894. y Applicationfiled January 14:,` 1893. Serial No. 458,328.-(No model.)

To all whom t may concern:

Be it known'that I, HENRY l-I. FEFEL, a citizen of the United States,residing at New York, in the county and State of NewYork, have inventednew and useful Improvements in Sewing-Machines, of which the followingis a specification.

This invention relatesto an improvement in sewing machines and theinvention consists in certain novel details of construction set forth inthe following specification and claims and illustrated in the annexeddrawings in Which Figure 1, is aside elevation of the machine. Fig. 2,is a section along :c w Figs. l and l. Fig. 3, is a section along y yFig. 2. Fig. 4, is a section along z e Fig. l. Fig. 5, is a de- Y tailface view of a trimmer. Fig. 6, is an edge view of Fig. 5. Fig. 7, is asection along w w Fig. 6. Fig. 8, is a front elevation of the machine.Fig. 9, is a section along u u Fig. 8. Fig. 10, is a section along u uFig. 9. Fig. 11, is a detail side elevation of the looper and adjacentparts. v

In the drawings, the letter A indicatesv a base or support from whichrise standards Bl supporting a cloth plate C. The goose neck D isprovided with a'presser bar E and presser foot F actuated by lever Graswell known. The driving shaft H has a driving pulley I. A suitableeccentric on said shaft'actnates link K giving motion to lever LMfulcrumed at N and linked or connected at O to the needle bar P foractuating the latter with its needle Q. A cam R on driving shaft H givesthe up and down motion to the feed dog S. The driving shaft has fixedtoits forward end a crank pin T (Figs. 8 and 9) connected by link U to ahorizontally oscillating lever or frame V fulcrumed at W and having thefeed bar X extending to the feed dog S for giving the latter a forwardand backward movement. The link U is made in two parts or sectionsconnected by screw thread Y so as' to be properly adjustable in length.Said link U is adj ustably connected to the lever or frame V by apin andslot connection ZEl so that said link U can be setto vary the degree offeed. The feed bar X is connected to the lever V by a pivot or joint h.The looper c acts in connection with needle Q and feed S to form alineof stitches. Saidlooper chas a forward and backward motion being mountedon a slide d reciprocating `on a support .or guide e. The slidecl isactuated by link f connected to saidlslide and to the arm g (Fig. 1)extending from lever L M. The guide or bar e is supported at. or nearone end by a pivot or joint'h so as to be capable of acertain swing forgiving thelooper its lateral movements in addition to its forwardand'backward play. The pivot or jointhis supported on a bracket t' adjustably held by set screw 7c in a post or standard B in which saidbracket t' can be adjusted or set to the proper position. The forward orfree end of guide e is provided with an a'rm Z into a slot in whichextends a point or guide pin m supportedby bracketfn.. Said last namedbracket n can'also be adjusted in a postB by means of set screw 0.` Thelateral play or swing of guide bar e is obtained from an eccentric p ondriving shaft I-I.

From said eccentric p extends a link or connection q made in two partsor sections connectedby screw thread r so as to be adjustable in length.Said link q connects by a ball joint s with the guide e said ball shaving a stem t engaging the guide e. The link is connected at one endto the eccentric by a strap or band extending in the usual way from theend of the link about the eccentric, the other end of the link being:jointed or.` pivoted to the part of the mechanism to be actuated bysuch eccentric. The socket part of link q in which is seated the ball sis split or partly so and held together by a screw it on removing orloosening which the ball s can be removed.l The socket part of link q isthen free to be turned one way or another along screw thread r untilproperly adjusted. The lateral play or swings of guide bar e derivedfrom eccentric p are imparted to looper c so that the latter has alateral movement or swing in addition to its forward and backwardmotion.

In the formation of a stitch the looper makes the' well known fourmotions. The needle having pierced down into the cloth forms a lloop ofthe needle thread and the looper then the feed of the cloth so that theneedle on its redescent will enter the loop of the looper thread. Thelooper then recedes cast-ing off the loop of needle thread, the needleon completing its descent setting the stitch then formed or in otherwords, tightening or drawing in the slack of the thread forming such`stitch. The looper then moves laterally in the direction of the feed ofthe cloth so that on its next forward stroke it takes the next loop ofthe needle thread.

A trimmer U is secured to a bar 0r carrier A' by means of a screw orfastening B. The carrier A' has a series of fasteningsor attachments Bso that the trimmer c can be set at various points as required. Thetrimmer can thus be set to trim before or after sewing as required. Thecarrier A plays on guides or posts C "on the cloth plateCandfsaiclcarrier A is provided with Tspli-t bearings which can be tightened byscrews D to take -vup the wear. A pitman 'or link E `carries umotiondirect from drivingshaft H by meansof eci centric F to the -carrierA andtrimmer fu.

The linkisfconnected at one end to the ec-` centric by a strap or bandextending' in the usual way from the end of the link about theeccentric, the 'other end of the link being jointed `orpivoted to thepart of themechan-l ism `tube yactuated `by Vsuch eccentric.

'.llheact'on of the cutting edge G of trim-` posedo'f ra pin H having asharp free `eX- i tremity or poi-nt to pierce 'or penetrate Vthe cloth`before the cutting edge G begins to act,

whereby the `cloth is held against derangement during trimming.

In Fig. 7 isshown a pieceo'f cloth I partly trimmed and engaged by thecloth-piercing pinIiI and having a row'of stitches at Kf Thecloth-piercing pin H is shown detachablysecured to trimmer U by a screwor fastening It. i y

The'cutting edge G of trimmer v with its cloth-piercing pin I'I islocated above the cloth plate C and said edge G acts in connection withthe edge M (Fig. 2) `of the 1 counter blade N -to trim or shear themate- The counter blade N is located below the plate C and is adjustablyheld in place by means of the screw and slot connection OP securing thecounter blade N to a depending flange or shoulder Q on cloth plate C.

The needle thread R is fed from any suitable spool or supply throughtension and by guides'as usual to the eye of the needle near its point.The looper thread S is similarly fed and guided as seen and passes undercloth plate C through an eye or guide T secured to base A and thencethrough an eye in the looper near its point or free end.

The cloth plate C is slotted or perforated or provided with thecustomarythroat plate 'f to allow play for the` needle, the feeder and thetrimmer.

Byadjustablyjsecuring the guide T 'as by l means of a screw Aand sloticonnection U V lsaid guide T can be set toward Yer from the `looperpoint as required.

I do fnot Vhereinclaim the looperlmecha'lrism described and shown, as it"constitutes the subject-matterof a separate 4applicatieri for patenti'ledby me .lune `22, 1893, Serial No.

What I claim as new, and desi-re to secure by Letters Patent, isdan l.The combination `with a stitchforming mechanism, of a-trimmer-,Iand acloth `piercer Amounted thereon in Ajunta'p'osiftion `to its cuttingedge `for `piercing the cloth 'when the trimmer descendaand uthusholding thelcl'oth against displacement wlhile "bei-ng trimmed,

substantially las described.

2. The combination with a1 cloth plate` and astitch forming mechanismsubstantially as described, ot' a trimmer provided with fa.

prickeror point located above the Iplatc and made tooperate throughavsloto'r passage in said plate for `piercing intothe goods to :hold

.the latter 'during the yaction of Athe trimmer,

and acounter blade `for said trimmer Vlocated below the plate,substantiallyas described.

In testimony whereof I have liereuntoset my hand in the presencelof twosubscribing Witnesses.

HENRY H. FEFEL.
